MULTIPLE-WRITING MACHINE.

Specification of Letters Patent.

T0 all 'whom t may concern.'

Be it known that I, FRANK AMos JOHN- soN, a citizen of the United States, and a resident of Dunellen, in the county of MiddleseX and State of New Jersey, have invented certain new and useful Improvements in Multiple-riting Machines, of which the following is a specification.

My invention relates to multiple writing machines. It is designed especially for a hand-operated machine and is intended to facilitate the production of true autographic signatures, which have all the characteristics of a single signature made in the ordinary way.

Referring to the accompanying' drawings: Figure 1 is a plan; Fig. Qis a front elevation with the pilot omitted, the pen-bar showing in section and with the pens turned around at right angles to the pen-bar, and Fig. 3 is a partial left elevation.

A pen-bar 1, is connected by pantographic links 2, 2 and 3, 3 to a rocking bar 5, which bar is mounted in front and rear boxes 6 on a bed plate 7-the links being joined by a tie bar 4:. On the front end of the rock shaft is an arm 8 to which is attached a spring 9, which tends to rock the shaft and raise the pen-bar upward into an inclined position. The pens 79, are mounted to turn on vertical axes and they are connected together by a link which is attached to an arm on the stem of the pilot; so that, as the pilot is turned in writing-varying the horizontal writing angle-all the pens will turn with it and they will maintain the same angle or relation to the general direction or line of writing. The pen mountings 10, are adjustable on the pen-bar and have upper and lower bearings 11, for the vertical portions 12L of the pen rods 12, which rods inclose and carry the pens. The upper and horizontal portion of each pen rod carries a sector 13. The pilot 14E is hinged to a stem 15 which turns in upper and lower bearings of its forked coupling 17, which is attached to the pen-bar. On the upper end of the pilot stem 15 there is an elbow lever 18. A connecting rod 19 joins all the pen sectors 13 to one arm of the elbow lever.

It will be noticed that the writing point of each pen is directly below and in line with the vertical portion, 12a, or axis of the pen rod; so that, as the pens are turned on their axes, the points do not move or travel over the writing surface.

From the above construction it is evident that, as the pilot is turned in writingchanging the angle which it makes with the general direction or line of writing-that all the pens will turn in unison with it. This construction gives the natural turn of the pens to produce shaded lines, which helps largely in producing the individual characteristics of different writers.

The pens and pilot may be turned around to the position shown in dotted lines in Fig. 1 and the connecting rod 19 changed to the other arm of the elbow lever and fastened to the sectors in the holes marked 20, so as to avoid dead centers. When so adjusted, the machine would be set up for writing a plurality of signatures on the same horizontal line. That is, the machine, when adjusted as shown in Fig. 1, will write a plurality of parallel signatures (one above another) and when adjusted as shown by dotted lines in the same figure will write a plurality of tandem signatures-one after another on the same straight line.

I claim, for use in a machine of the class described:

1. In a machine of the class described, apen-bar; a plurality of pen-carriers mounted to rotate on vertical axes on said bar; a corresponding plurality of pens mounted in said carriers; in combination with means for simultaneously rotating said pen-carriers on their vertical axes to vary the horizontal writing angles of all the pens.

2. In a machine of the class described, a pen-bar; a plurality of pens; pen-carriers for said pens; a pilot stem-said pilot stem and said pen-carriers each being mounted to turn on said bar; a guide handle for said pilot stem, by means of which said stem is turned; in combination with means for turning the pens in unison with the turning of said pilot stem.

3. In a machine of the class described, a pen-bar; a. plurality of pens; pen-carriers for said pens; a pilot stem-said pen-carriers and said pilot stem each being mounted to turn on said bar; in combination with a guide handle for said pilot stem; a plurality of armsone connected to each of said pencarriers and one to said pilot stem; and a connecting link joining the arms of said pen-bar; a pluralityof pens; a plurality of pen-carriers pivoted on Vertical axes on said pen-bar; in combination withl a pilot con.- troller and connection from said controller which is adapted to turn said pen-carriers on,

their axes.v

5. In a machine of the class described, a pen-bar; a plurality of pens; a plurality of pen-carriers mountedl on vertical aXes on said pen-bar; in combination with a linksaid link being connected to each of sa-id pen-carriers, whereby said pens may be adjusted to simultaneously Write either a plurality of parallel O r a plurality oil tandem signatures.

6. In a machine of the class described, a penebar; av plurality of pens; `a plurality of pen-carriers rotatably mounted on said bar; in combination With a plurality 0I" sector arms-one for each pen and a link connecting the sector 'arms-each of said sector arms being pivotally attached to said link.

7. In a machine of the class described, a

(legales of this patent may be obtained for penfbar; a plurality "of" pens a4 plurality of i@ pen-.carriers rotatably mounted on Vsaid bar;

avpilot o r controller also mounted on said bar; in combination With a connecting link-said link being pivotally connected to each of said pen-carriers and to said pilot, Wherebysaid pens may be adjusted to simultaneously Write a plurality of parallelw ,signatures or a plurality of tandem signatures and at the same time be guided to Vary the horizontal Writing angle of all the pens.

8. In a machine of the class described, 1a l pen-bar; 'a plurali-ty of pens; a plurality of pen-carriers rotatably mounted o nsaid penbar on Vertical' aXes; in combinationwith means for turning all of said pen-'carriers on their aXes in unison-the pens being mounted in the carriers so that each of the Writing points is in line With the Vertical axis of its' pen carrier.

In testimony whereof If aiiiX my signature in presence of two Witnesses.
